UNITED STATES STEPHEN FRONRATH, OF DETROIT, MICHIGAN.

DOOR-HOLDING DEVTCE.

Application filed January 20, 1923. Serial No. 613,851.

Large hinged doors, such as used for garages, hangars and other buildings are at times difiicult tomaintain in open positions because of wind pressure and consequently such doors are very often injured by being slammed open or shut and at other times automobiles, aeroplanes, and even persons are injured by such doors. \Vedges, obstructions and other devices have been user to prop such doors open but such devices are not at all times convenient,therefore it is believed that any door that is equipped with av stop, prop or holding device will be adesideratum.

My invention aims to provide a simple, durable and inexpensive holding device that may be mounted adjacent the lower edge of the door and supported in an inactiv position when the door is closed, otherwise the device occupies an active position to prop and hold the door open. The device, in its preferred form, is made of plumbers fittings, easily obtainable and such fittings can be easily and quickly assembled to provide a device that will lend very little weight to a door and prove advantageous and satisfactory as door hardware.

My invention will be hereinafter specifically described and then claimed, and reference will now be had to the drawing, wherein Figure 1 is an elevation of a portion of the door provided with a holding device, showing it in an active position by full lines, and an inactive position by dot-ted lines;

Fig. 2 is an enlarged plan of the device in an active position;

Fig. 3 is a front elevation of the same, and p Fig. 4 is a vertical sectional view of the device as applied to a portion of a door.

My door holding or stop device comprise a set of socket members 1 which are circular in elevation and have the marginal edges or lateral flanges thereof provided with counter-bored openings 2 for screws 3 employed for securing the socket members, in spaced relation, on the inner wall of a door 4, above the lower edge of said door and adjacent the outer edge thereof, as bestshown in Fig. 1. The socket members 1 have concentric openings 5 with the walls thereof screwthreaded to receive short supports 6 which are preferably in the form of short pieces oi pipe or tube having the ends thereof exteriorly screwthreaded.

Mounted on the outer ends of the supports 6 are elbows 7 which are adjusted to be firmly held by the supports 6 in horizontal planes with the outer ends of said elbows confronting each other so as to be connected by a spacing connector 8 having its endsscrewed into the elbows, said connector being preferabl in the form of a short pipe or tube.

oosely mounted on the connector 8 is a T member 9 which is placed on said connector prior to attaching the elbows 7 to said connector, and mount-ed in the T member 9 is a leg 10 in the form of a long pipe or tube. The leg 10 is of a greater length than the distance from the lower edge of the door 4 to the socket members 1 and with the T 'member 9 supported a. short distance from the inner wall of the door 4, the leg 10 may be in an activeposition, as shown in Fig. 4 or it may be swung upwardly to rest against the door in an inactive position, as shown by dotted lines in Fig. 1. The leg occupies this position when the door is closed and when the door is opened the leg is swung downwardly to engage the ground, pavement, floor or surface under the door to serve'as a. prop in holding the door open against any wind pressure at the outer wall of the door. The use of a T member and a pipe in this manner permits the substitution of longer. or shorter pipes as required without any special preparation.

From the foregoing it will be observed that the door holding or stop device is composed of plumbers fittings, but I do not care to confine my invention entirely to such fittings, because an elbow, support and socket member may be av one-piece casting and two of such castings used and suitably connected for supporting the T member and leg. Therefore, I reserve the right to make such changes in the size, shape and manner of assembling the parts of my device as are permissible by the appended claim.

Nhat I claim is 2- A door holding device comprising spaced apart socket members in a horizontal plane, elbows connected to said socket members and arranged With confronting ends in the same plane as the socket members, a connection between the confronting ends of said elbows and a depending leg having its upper end pivotally supported by said eonneetion and adapted to be swung upwardly 19 at an inclination to the perpendicular.

In testimony whereof I afiix my signature.
